How do you solve the equation in the sixth grade of primary school? FOR EXAMPLE: 9X 4X 20 93. To sol

Move the item and put the same item on the same side. 9x+4x=93+20 merge similar items. 13x=113

The coefficient is one. x=113/13

Note: If there is a formula with a denominator in the equation, the denominator should be removed first, the parentheses with parentheses should be removed first, and the denominator should be removed first and then the parentheses should be removed if there are both).

9x+4x-20=93

13x-20=93

13x=93+20

13x=113

x=11313

x=The equal sign should be aligned up and down! ）

1 Move the unknown to the left and the number to the right (sign change): 9x+4x=93+202 Addition and subtraction of similar terms: 13x=113

3) Multiply or divide by the same factor on each side, and the product remains the same: 13x 13=113 13x=113 13

The question is 9 x = 6

Let's replace x with () so that the child can see it at a glance.

It can be written as 9 ()6, and according to the formula – the divisor of the dividend quotient, we can get () 9 6

So () i.e. x = can be written directly this way if you take the exam.

9 x = 6 solution: x x 9 = 6 x

1 9 6x (both sides are multiplied by x at the same time, why do you need to multiply both sides, you will know when you reach junior high school).

x=9 6, i.e. x=, we can also think backwards.

9÷（？=6, then 6 (?) 9, according to the formula – the multiplier quotient multiplier, we can get.

So it's important for a child to learn to think more than once!

5*So x=

x+solution: x=

x=x solution: x=

x=Solution: 5x=

x=x=3x-15×4=348

Solution: 3x=348+60

x=408÷3

x=5x=5x=15x=3

x=650-35, get x=615

5x= x=

10x= x=

x=x*3/4=3/2-1=1/2 x=2/32x=7/8-5/8=1/4 x=1/8

x*3/4=3/10 x=

72-48÷x=56

48÷x=72-56

48÷x=16

x=48÷16

x=332-x＝12

32-x＋x＝12＋x

32＝12＋x

12＋x－12

Use column equations to solve problems encountered in real life!

1. Solve equations.

4x+2、Is the following solution equation correct? Fix what is wrong. 4x-4=6 5x+

Untie. 3x=24

Untie. 5x+x=8 5x=

5x=10x=2

3. Column equation solution application problems:

The school bought. Box of chalk, use go.

After the box, there is still left.

boxes, on average more per box. Less box?

There are a total of students in the fourth grade.

people, extracurricular activities, 80

Famous girls all go skipping rope. Schoolboy. Divide into.

How many people are in the group on average?

The canteen arrived. kilograms of rice, than shipped flour.

times less. Kilogram. Canteen transport.

24x+180-32x=102

180-102=32x-24x

8x=78x=39/4

Here's how it goes: 40%=, so the equation can be written like this:

x x= [The dividend is equal to the divisor multiplied by the quotient] x=

Multiplication is calculated first, and then the term is shifted, that is, the coefficient is reduced to 1 and both sides are divided by 3 at the same time.
